Product description
The Airmax Shallow Water Series SW20 is an ultra-efficient aeration system designed for ponds and lakes up to 1/4 acre with a maximum depth of 6 feet. Powered by a whisper-quiet LR25 Linear Diaphragm Compressor, the SW20 delivers 2.5 CFM of oxygen through two ProAir 2 Weighted Diffusers. Specifically optimized for shallow water environments, this system eliminates stagnant zones and promotes muck decomposition through increased dissolved oxygen levels. Housed in a natural faux-rock ETL-certified composite cabinet, the SW20 offers extreme energy savings, costing approximately $3.60 per month for 24/7 operation.
Efficient Aeration for Small & Shallow Ponds
SilentAir LR25 Linear Compressor
The LR25 Linear Diaphragm Compressor is the heart of the SW20, designed specifically for high-volume airflow at shallow depths. Operating on just 50 watts, this 115V compressor is a leader in energy efficiency. It features specialized rubber mounts that virtually eliminate noise and vibration, making it ideal for residential areas. The LR25 is built for continuous use, ensuring your pond stays oxygenated around the clock with minimal impact on your utility bill.
Heavy-Duty Composite Cabinet
Every SW20 comes with an ETL-certified composite cabinet that provides maximum protection while blending into your pond-side landscape.
- Weather Protection: Features a high-density air intake filter and a cooling fan with a rain shroud to protect the engine from moisture and overheating.
- 2-Port Manifold: Includes nickel-plated ball valves for precise airflow adjustment, pressure relief valves, and quick-disconnects for easy maintenance.
- Remote Versatility: The system can be installed up to 1/4 mile from the shoreline, eliminating the need for power at the water’s edge.
ProAir 2 Weighted Diffusers
The system utilizes two ProAir 2 diffusers to ensure balanced circulation across the pond floor.
- Fine Bubble Technology: PTFE-coated membrane sticks release micro-bubbles to maximize oxygen transfer.
- Low Maintenance: Unlike air stones, these membranes resist clogging and do not require acid washing.
- Stability: An integrated check valve prevents back pressure, while the innovative sled design keeps the diffuser upright on the pond bottom.

For the most effective muck reduction in shallow water, space your two ProAir 2 diffusers evenly across the pond floor. Clustering diffusers in one spot reduces their coverage area; balanced spacing ensures the entire water volume is circulated, preventing "dead zones" where algae can thrive.
